The EMX PROBE-200 is a replacement or installation sensing probe for the EMX CarSense 101 vehicle motion detector system. Manufacturer number EMX-1820-1 identifies the probe configuration with a factory 200 ft lead for installations where the sensing point is located a substantial distance from the CarSense 101 controller.
The probe uses magnetic vehicle sensing technology and is installed along a driveway, roadway, gate entrance, parking lane, or similar vehicle path. As a moving ferrous vehicle passes through the detection area, the probe senses the change in the surrounding magnetic field and sends that information to the compatible CarSense 101 control module.
Do not assume compatibility with other EMX vehicle detectors simply because they also use magnetic sensing. PROBE-200 is associated with the CarSense 101 system and should not automatically be substituted for an LRS sensor, VMD202 detector, inductive loop, or another probe family.
The PROBE-200 is the sensing probe and attached lead only. It does not provide a gate activation relay by itself. A compatible CarSense 101 controller is required to power and monitor the system and provide the output connection to the gate operator, parking barrier, overhead door, security panel, warning device, or other compatible equipment.
EMX identifies the CarSense 101 controller as an 11-pin plug-in module with adjustable sensitivity, adjustable off-delay, LED indicators, and DPDT relay outputs.
The CarSense 101 is designed as a vehicle motion detector. EMX specifically notes that a vehicle must be moving near the probe for reliable activation. It should not be selected as a substitute for a detector specifically required to maintain continuous detection of a stopped vehicle.
This distinction matters on automatic gate systems. Free-exit activation is different from entrapment protection, reversing-loop operation, or other applications where dependable stationary vehicle presence may be required.

The PROBE-200 connects to a compatible CarSense 101 controller. Current EMX specifications for the CarSense 101 platform include:
These are controller specifications, not electrical ratings for connecting the PROBE-200 directly to another device. The sensing probe should be connected only according to the CarSense 101 wiring instructions.
The sensing function is associated with the same CarSense 101 family, but the factory lead length is an important ordering difference. Select the probe that reaches the controller location without assuming the buried sensor cable should be altered or extended in the field.
One of the primary CarSense 101 applications is free-exit vehicle detection. A properly installed probe can detect an approaching moving vehicle and allow the CarSense controller to provide an activation signal to a compatible gate operator or access-control system.
The actual gate input used must match the intended control function. Do not connect the detector to a safety, obstruction, or monitored entrapment input simply because an available terminal is present.
The probe responds to changes in the magnetic field, so placement is important. Moving ferrous objects other than vehicles may also affect the probe.
EMX troubleshooting guidance specifically calls for the probe shield and earth ground to be properly connected at the CarSense 101 controller to help reduce unwanted electrical noise.
If a system begins false-triggering after previously operating correctly, inspect the probe lead for damage and check the shielding, grounding, nearby electrical equipment, power supply, sensitivity setting, and surrounding metal before replacing the probe.
EMX currently specifies approximately 845-1055 ohms across the red and black probe conductors when checking a CarSense 101 sensing probe. There should be an open circuit between the shield and each signal conductor.
Electrical diagnosis should be performed with the probe disconnected from the controller and system power handled safely. If the wiring or electrical conditions are unclear, have the system tested by a qualified gate or access-control technician.
Similar vehicle detection products may use different sensing technology, controllers, outputs, wiring, and detection behavior. Verify the existing system before changing sensor types.
The CarSense 101 controller, 11-pin socket, HAR-11 harness, gate operator, conduit, junction equipment, power supply, and other installation components are not automatically included.
If a CarSense 101 controller shows detection when nothing is moving near the probe, check for a damaged probe cable, excessive sensitivity, electrical noise, overloaded controller power, improper shield grounding, nearby power lines, transformers, or moving steel before replacing the PROBE-200.
If the controller does not detect a vehicle, verify the probe resistance and wiring and remember that EMX states the CarSense 101 requires vehicle movement near the probe. It is not designed as a stationary vehicle presence detector.
Install the probe according to current EMX CarSense 101 instructions so it remains stationary and properly oriented relative to the vehicle path. Protect the direct burial lead from physical damage and keep it separated from power wiring.
Locate buried utilities and electrical conductors before trenching, excavating, drilling, or cutting pavement. If the existing controller wiring cannot be positively identified, have the installation serviced by a qualified gate or access-control technician.
The PROBE-200 is part of a vehicle motion detection system commonly used for free-exit and activation functions. It is not a monitored entrapment-protection device and should not be used as a substitute for required safety equipment.
Never bypass required photo eyes, monitored safety edges, obstruction sensing, emergency access, fire access, or other gate operator safety circuits when installing or servicing the CarSense system.
The PROBE-200 is a direct burial magnetic vehicle sensing probe with a 200 ft lead for the EMX CarSense 101 / CS-101 vehicle motion detector system. It is commonly used for free-exit gate activation and other moving-vehicle detection applications.
No. PROBE-200 is the sensing probe and attached 200 ft lead only. A compatible CarSense 101 controller is required to process the probe signal and provide relay outputs to the gate operator or other equipment.
The primary difference is factory lead length. PROBE-150 uses approximately 150 ft of lead, while PROBE-200 uses approximately 200 ft. Confirm the distance between the probe and controller before ordering.
The CarSense 101 is designed as a vehicle motion detector rather than a continuous presence detector. EMX states that the vehicle must be moving near the probe for detection, so it should not be relied on for applications requiring dependable stationary vehicle presence.
No. The probe is designed to connect to a compatible CarSense 101 controller. The controller processes the probe signal and provides the relay output used by compatible gate, door, barrier, or access-control equipment.
Possible causes include damaged sensor wiring, excessive sensitivity, improper shield grounding, electrical noise, overloaded controller power, nearby power lines or transformers, and moving ferrous metal such as a steel gate or barrier mechanism.
Do not assume compatibility. PROBE-200 is associated with the CarSense 101 system. LRS and VMD202 products use different detector designs and should not be substituted without exact manufacturer documentation confirming compatibility.
No. PROBE-200 is part of a vehicle motion detection system and must not replace required monitored photo eyes, safety edges, entrapment protection, or other gate operator safety devices.
